The White Light Chakra Sabre was a tantō that originally belonged to Sakumo Hatake, who passed it on to his son, Kakashi. It was a straight-bladed tantō with a small, circular hand-guard. It gave off a white streak of chakra when it was swung, thus earning Sakumo his title of "Konoha's White Fang" (木ノ葉の白い牙, Konoha no Shiroi Kiba). This blade was destroyed during the Third Shinobi World War during Kakashi's fight with Kakkō.
